a way to change sortComparer in entityAdapter?

[kuk941025]

Hi! :)
I am trying out entityAdapter, and want to dynamically change sortComparer.
Heres what I tried, but didnt worked out.

const adapter = createEntityAdapter({
  selectId: (itemList) => itemList.id,
  sortComparer: (a, b) => a.createdAt - b.createdAt;
});

const slice = createSlice({
  name: 'test',
  initialState: adapter.getInitialState(),
  reducers: {
    changeOrder: (state, action) => {
      chatInfosAdapter.sortComparer = (a, b) => b.createdAt - a.createdAt;
    },
  },
}

I wanted to test this before I apply more complex sort comparer logic in entityAdapter.
What will be the right way to change sort comparer?

btw, i am also trying out rtk-query and loving it so far! cant wait for ssr support 🙏
Thanks!

Not possible at the moment, sorry.

createEntityAdapter creates a closure, and there's currently no way to change the sorting behavior after creation.

You could in theory create more than one adapter with different sorting methods, and switch which one you're using:

if (someCondition) {
  sortByNameAdapter.upsertOne(state, action)
} else {
  sortByDateAdapter.upsertOne(state, action)
}
